Local Environmental Conditions
Around the heart of City of Kwinana, a mix of built-up land and open space means traffic is an important, but not overwhelming, local pollution source. The surrounding woodland releases natural compounds that, in warm sunny weather, help form ozone. Winds here are fairly strong, averaging around 25 km/h, which helps disperse local pollution. Air arriving from elsewhere in the region adds to what is produced locally.
Hot afternoons from December to April, averaging 24°C in the warmest month, are when ozone is most likely to build up. Later, cooler, still evenings from July to September, averaging about 15°C, tend to hold exhaust close to busy streets. The risk of wildfire smoke peaks from November to April, when dry vegetation burns easily. Breezy weather in January, with winds near 25 km/h, tends to sweep pollution away.

When is air pollution at its worst in City of Kwinana?
Hot afternoons from December to April, averaging 24°C in the warmest month, are when ozone is most likely to build up. Later, cooler, still evenings from July to September, averaging about 15°C, tend to hold exhaust close to busy streets. The risk of wildfire smoke peaks from November to April, when dry vegetation burns easily. Breezy weather in January, with winds near 25 km/h, tends to sweep pollution away.
Are air quality levels in City of Kwinana based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
Understanding the Scale
The 0–100 air quality scores represent risk levels, not direct air pollutant concentrations. Higher scores indicate higher risk.
Air Quality
| Good | 0-20 | Low air quality risk. Air quality is expected to be good, with low levels of pollution. |
| Fair | 20-40 | Generally low air quality risk. Air quality is expected to be acceptable, with some pollution present. |
| Moderate | 40-60 | Moderate air quality risk. Air pollution is elevated and air quality may be less favorable. |
| Poor | 60-80 | High air quality risk. Air pollution is high and air quality is expected to be poor. |
| Very Poor | 80-100 | Very high air quality risk. Air pollution is very high and air quality is expected to be very poor. |
